I wore these boots about a week before I really used them. I had no problems in Belize, hiking in the mud 6 miles on multiple days. My feet never got wet despite the mud and puddles. If I had to complain, it kept my feet pretty warm in the humid weather. However, I never got a blister, or even a hot spot.

Comfy? Yes. Able to withstand 100% slopes? Not so much. Within one month, the soles completely split on both boots, right across the ball of my foot, Not recommended for heavy off trail use.

My husband bought me these boots after His dog chewed up my Northface boots. I wasn't so sure about these boots at first. But let me tell you, we have had mountains of snow this winter. Really 9 feet of snow. I have shoveled so much snow I have the best arms in work out history. And these boots have been on my feet every inch of the way. Our drive way is half a football field long, I have shoveled it in these boots & my feet stay warm & dry. I have worn these boots on our icy roofs covered with 3 feet of snow, and my feet have stayed warm & dry. And, these boots are so comfortable. From day one I have not had one single blister or sore spot & I have put miles on these boots. I like them so much I just had to buy another pair as a back up. I don't want to be without my boots ever again.

My wife bought these one month before our trip after her pair of 10 year old Vasques blew out. We thought the softer leather would break in quicker. She loved them and with some gore-tex gaiters they kept out all the scree, dust, and mud the mountain could throw at us. She was warm on the summit at 0 degrees (f). I bought the sturdier all leather vasques 8 months before our climb and I think they were just getting broken in by the time of the trip.

These boots are simply amazing! I decided just weeks prior to my hike that I needed a new pair and decided on the Wasatch even though I "thought" I wanted something lighter in weight. I got them 2 days after I placed the order - shocked! They only got a little bit of wear on some small hikes before I headed up the long hike of Yosemite's Half Dome and performed beautifully!! They gripped the granite perfectly up the cables and just as well coming down. Superb ankle support along all that bumpy terrain and climbing of steps. With all the water coming off both of the falls, these boots never leaked water to the inside. No blisters, and it was a long hike. I LOVE THEM! My husband even purchased a pair in men's after I got home.

Wore these around the house for about a week, but they felt comfortable from day 1. Went on a couple of little hikes and snowshoe trips and they were lovely. We hiked the 5 mile, 5000 ft elevation gain up Mt. Rainier to Camp Muir last weekend and they rocked! Totally comfortable, no hot spots, the perfect fit. I actually had bought them without trying them on in a store first and bought based on the other reviews. They have been excellent. I'll likely buy a second pair to have when these ones wear out.

For anyone that has doubts about this boot, don't sweat it. I actually bought my boots in an outdoor store, because I like to try them on first before I buy. I have a wide foot, so I was expecting my boot shopping to be a pain. In this outdoor store they only had the Vasque Wasatch for womens boots. I was leery that they would work. Anyway, I tried them on, and they fit "like a glove". I honestly have never had any kind of shoe fit me that well. I thought it was too good to be true.
Well, I've been wearing these boots from day one, because these are my working/hiking boots. I have worked long hours at a visitor information desk, and have abused my boots on countless miles of trails. I live in the southwest-in slickrock country- so the territory can be real harsh on shoes.
These boots really are meant to last. You can barely even tell the extorior upper portions are worn. The vibram soles are alittle worn, but that is to be expected, for all the use they have received.
And for wet conditions? I went snow shoeing in Mesa Verde NP, after a huge snowstorm, on a fresh foot + of snow. I expected some discomfort and wetness. Nope. Not a drop. And I'm now up in Bryce Canyon NP, where they still are seeing snow into late spring. My feet are staying nice, dry, and protected.
How about summer? I use to wear sandals, and thought that was most comfortable. But since my boots fit like a glove, I don't plan on going back to sandals for summer. The best option: go buy some lightwieght socks for summer wear. I've already done that, and yep, the boots do fine in warmer clims.
Bottom line: Not everyone has the same feet, but for me, these boots fit real well, are durable, are meant to last, and oh ya-make you look like a hip outdoor chick!
